To a/ZZ whom it mag/concern.-

' Be it known that I,.WILL1AM JOHN' HER- ALD, of the city ofHamilton, inthe county of Wentworth, in "the` Province of Ontario,

Canada, have invented certain new and useful improvements in Wire-Drawing Machines,

' of which the following is'thespecijication.

.My invention relates to improvements in W redrawing machines and the object of the invention is to devise a form of drum for drawing the Wire whereby all 4slipping or abrasion of lthe Wirel will be" eliminated no i matter what variation there may be in the 'C' the opposing dies.

D is one of he unter-gears forming the drive, which it is not necessary here to describe. v

speed or call of the WireWithin-c'ertain limits.

Further objects lare to provide a device as set forth above that Wiel provide for Wet or dry Wire-drawing, in which the Wire will pass from one die to the other With a minimum amount of pull, and in Which anyI s ip will not result in the Wire contracting; and

a further object is to provide a simple means whereby thewear mayb-e taken up.

To eiiect these objects, I have constructed -a drum having the face and periphery slitted radially and axially, said drum being of spring metal, and afriction-gear held on the shaft With a suitable 'key and adjustable thereon, the parts being otherwise constructed and 'arranged lin detail as hereinafter more particularly explained.

.Figure is a lpian view of my device, showing' the Wire in position to be drawn around'v the drum. Fig.' 2 is a sectional-elevation ofthe device shown in Fig. 1. Fig. 3 is a perspective detail of the drum. Fig 4 is a vertical section of the drum, taken on the line:1:g/,i*`ig.3-

in the drawings like letters (3f-reference' indicatecorresponding parts in each iigure.

A represents a portion of a frame of a Wiredrawing machine.` B theshaft, and C and E s 's the drum, having the hub Ev suitably secured to the shaft. The face E2 is curved at the outer end and merged into the periphery, which is provided with an annular` projec'tion E3, form-ing a groove YE?. .The drum is provided with slits E5, extending from` a point near the-hub -totheouter edge of the periphersuch .slits E5 extending radially the inner periphery of the drurnwith the periphery of the Wheel F.

around the drum and tangenti ally leads therefrom to thel dies C, through Which the Wire is drawn.

sion is required to pull down the drum on the Wheel, the sections between the slits and drums collapsing, or, in other Words, the slits drum and cause the frictional contactwith the Wheel F. The drum of course is secured tudinal displacement by the collar H.

' curs due to diHerent speeds of Wire, will take Wheel and not between the drum and wire, and Will not cause the Wire to -contact With sion Will be obviated no matter What varation .there may bein the s eed or calll ofthe Wire.v v The drum may o course be made very sensitive, and consequently act `most `from die to die.l

4 0f course it will be understood that there shaft,.and the dies and drums may be arranged alternately lengthwise of the machine. Necessarily, also, there will be a corresponding number of dies alined vvith their respec- `tive drums. It Will also be-.understood that .With the alined drums and diesA extending throughout the length 'of the machine there are several reductions made 'in the Wire.

not describe it specifically, as it forms -no Gis a Wire which passes one or more times' closing in order to reduce the diameter of the loosely on the shaft and is held from longi- It Wiil now be seen that any slip, which ocl place between .the drum and the frictionmay be several drums in. the' same cross-` a key F2 on the shaft, Which permits of the wear caused vby .the rictional contact of d It will be understood that an initial tenl itself, and consequently any chang'orabra- `eil'ectually in response'to the call of-.the Wire ICO As, this arrangement of the machine-is old, I do .los feature of my invention. Inrdeyr t Show l, l. Y

he function of the inyenon, have therefore conned the speooston and drawings to merely one drum and coasting' dies.

what I claim as my invention is- 1. The combination, with e, dmm loosely suppolted on a suitable Shaft and provided with slits extending rsdollyin the face of the dum and from one edge of the `elphelfy to lle otheredge,y of a {Tieton-Wheell secured on the shaft and with which the interior periphery of tlleodrum is adapted to Contact as the drum is oontraotedupon the call of the wire,

ss and for the purpose speeed.

./J. The Combination with a drum loosely q supportedoua suitable shaft and provided g with slits extendngradelly in Athe foce o 'he drum ond from one edge of the perplery to the other edge,sa1d drum la'lng mtemslly outwardly, of a friction-Wheel having a taper Silostanljially corresponding; so the internal Hare of the drum and adjestably secured on the shaft and with which ille interim periphery of the drum is sdaptocl to Contact as the drum is contracted upon the oall of the wire, as and for the purpose specified.
